During Sunday's game against the Green Bay Packers, Chicago Bears QB Jay Cutler suffered a knee injury which caused him to miss almost the entire second half. The reaction to Cutler sitting has been intense to say the last. Former players took to Twitter to criticize Cutler who is also hearing questions about his toughness from media and fans.

Now we know what the knee injury was that kept Cutler out -- a reported MCL tear. The Bears decision to sit him makes a little more sense now. 

Like LB Brian Urlacher, Bears S Chris Harris backed the decision to keep Cutler out and said there was no need to question his toughness.

"The guy plays through diabetes every day," Harris said, "if that's not tough then I don't know what is."

Harris said Bears players were "absolutely" confident in Cutler and said those criticizing him need to "chill out". After news of Cutler's torn MCL has come out, much of the criticism has quieted down.
